Double-Eye Leaf Springs
Double-eye leaf springs have eyes at either end of the spring assembly with nylon bushings to assist in
preventing wear. U-bolts hold the springs to the axle with a plate.
The articulation of this suspension occurs when the eyes rotate on the wear surfaces provided in eyes of the
springs and on the equalizers. This suspension is also available in single and multiple axle configurations.
In trailers with 2 or more axles, the additional movement is maintained by an equalizer. This feature allows
for even load handling from axle to axle.
Double-eye suspension systems are available on 8,000 lb. axles. Tandem and triple axle mounting kits are
available for both 33” and 35” axle spacing.
